DVD with 50 Gbyte capacity

A special alloy makes it possible to store up to 50 Gbytes, distributed over two layers, on a single DVD. They are very durable, which was not the case with such data carriers until now, and are often rewritable.

At the ISOM 2001 Symposium, Matsushita, better known here under the name Panasonic, wants a 50 gigabyte DVD Introduce capacity. The data density is made possible with a special blue laser. Until now, such media only had a very short shelf life. But the Panasonic DVD consists of two layers made of a germanium-antimony-tellurium alloy. As a result, the data carrier can be rewritten up to 10,000 times. Due to the higher data rate of up to 33 Mbit/s and the higher capacity, the new media are particularly suitable for DVD recorders.
